It should be. I have so far in 1+years have known of only 2 cases where the official scores were 10 points off. I save those for reference and to understand what can be improved for accuracy. However, the formula and calculation is pretty straightforward so I am not quite sure why there are these anomalies. I am aware of only 2 so far.

P.S. Something I have learned lately is that Official GMAT prep tests (practice ones) do not have their percentile updated to the latest version yet, just heads up.

Is this always accurate?
Hi bb !

First of all, thanks for the calculator I used it a lot during my preparation. Secondly, I wanted to update you on another case: I've just got 645 on the official test with Q79 V83 DI83 and the calculator gives me 635.

Thank you so much for the feedback! I have one report from a user who took a GMAT Prep with 80, 83, 82 taking GMAT prep that they got 645 which is the same sum as your score and this would indicate there is a slight anomaly around 245 points that I have probably manually adjust - did you take the official test, not a GMAT Prep, just to confirm?

Thank you.

Very true. I reported the first discrepancy, and I had a total of 245 as well (86+81+78).

Thank you Aryaa03 and gferis.

Now that we have 2 reports, I think it is safe to say this is the official score and the calculator should be changed.
I have put a manual condition that if the score sum is 245, then the score should be 645. The interesting part is that the raw calculated number is 633 using the same formula that works for every other combination except this one. Weird.

It is a head scratcher, but I am happy to adjust and follow the official pattern.

Thank you again. If anyone has any other questions or comments, absolutely would appreciate it!
-BB

P.S. I have 3 reports actually for this exact number! I got a report last week from nisheshj about the same combination.

Thanks BB. Calculator seems accurate with whatever results I have encountered. I have plotted Total score Vs GMAT score. It helped me, hope it helps others. Reference data points are taken from this calculator.





Regards,

Sai

I entered my recent official mock section wise scores. Overall score is matching exactly but the section wise & overall percentile differs by 2~3%.

When I entered my official mock scores, overall score is matching but section wise & overall percentile is less by 2~3 %

Thank you for the question.

I believe,That is because the percentiles in the gmat prep have not been updated since 2023.

You can look up your scores and then look up the new updated percentiles from August 2024 on mba.com and you can tell me if they match or if our calculator is wrong.

The calculator uses the percentiles from August 2024.
